Thank you
I am using a book, that are teaching me the different kinds of Kanjis.
The 下 was explained as: under, below and inferior. But I did understand the meaning of the word. I was just curious to hear, if it was that literal.
The book tho explains the inside with: 中．たか
So why 下 and not 中?
Inside, and under, is an interpretation. In Denmark we would say: Inden under. Inside under.
But what I do understand is, that when learning Japanese, you cannot be conservative in your way of thinking, or your knowledge of things.
You need to be able to make some leaps. The book I am using is showing with pictures how the kanjis originally came to be, and also the written way of the kun'yomi, and the om'yomi.
It has made it a lot easier for me, to make the rights connections
Look at it this way: your body is the surface and your shoes and clothing sit "above" your body. Your underwear and socks sit "below" or "under" your clothing or shoes. Same with "undercoat (of paint)" above, the building or object is the surface, the main layer of paint is "above" the surface, and the undercoat is "under" the paint.
